    4th International Conference on Open RepositoriesThis presentation was part of the session : DSpace User Group PresentationsDate: 2009-05-20 03:30 PM – 05:00 PMThis paper will provide three different cases or examples of how a mid-size University is able to implement DSpace across diverse groups of users. Additionally, one of the cases will show how the DSpace software has been 'repurposed' to serve as the university library's Electronic Reserve and how it has been linked the library's ILS. The paper will show how the university has obtained a consistent level of sustainability, preservation and accessibility to using DSpace with limited resources

    Federal Reserve Banks as fiscal agents and depositories of the United States in a changing financial environment

    Pursuant to the Federal Reserve Act, the Federal Reserve Banks perform a number of services for the United States and for other entities as fiscal agents and depositories. These roles have evolved since the relevant provisions of the Federal Reserve Act were implemented in 1915. An article in the April 2000 Federal Reserve Bulletin described these activities as being mainly the issuance and redemption of securities and the processing of payments to and from the federal government. Although the basic fiscal agent services have not changed since the article was published in 2000, considerable changes have occurred in the way those services are provided. For example, the Treasury and the Reserve Banks have implemented new web-based technology to improve the federal government's provision of services, much the same as financial services firms have used web-based technology to improve the ways that they do business and communicate with their customers. This article reviews the evolution of the Reserve Banks' fiscal agent role since early in the twentieth century, and describes fiscal agent and depository services today.Federal Reserve banks ; Financial markets

    Ultra-high temperature stability Joule-Thomson cooler with capability to accomodate pressure variations

    A Joule-Thomson cryogenic refrigeration system capable of achieving high temperature stabilities in the presence of varying temperature, atmospheric pressure, and heat load is provided. The Joule-Thomson cryogenic refrigeration system includes a demand flow Joule-Thomson expansion valve disposed in a cryostat of the refrigeration system. The expansion valve has an adjustable orifice that controls the flow of compressed gas therethrough and induces cooling and partial liquefaction of the gas. A recuperative heat exchanger is disposed in the cryostat and coupled to the expansion valve. A thermostatically self-regulating mechanism is disposed in the cryostat and coupled to the J-T expansion valve. The thermostatically self-regulating mechanism automatically adjusts the cross sectional area of the adjustable valve orifice in response to environmental temperature changes and changes in power dissipated at a cold head. A temperature sensing and adjusting mechanism is coupled to a cold head for adjusting the temperature of the cold head in response to the change in heat flow in the cold head. The temperature sensing and adjusting mechanism comprises a temperature sensitive diode, a wound wire heater, and an electrical feedback control circuit coupling the diode to the heater. An absolute pressure relief valve is interposed between the output of the cryostat and an exhaust port for maintaining a constant exhaust temperature in the refrigerating system, independent of the changes in atmospheric pressure

    We report progress on 115In+ and 137Ba+ single ion optical frequency standards using all solid-state sources. Both are free from quadrupole field shifts and together enable a search for drift in fundamental constants.Comment: 2 pages, 1 figure, submitted to IEEE/LEOS Summer 2005 Topicals conference proceeding

    Stellar abundances and molecular hydrogen in high-redshift galaxies -the far-ultraviolet view

    Full text link
    FUSE spectra of star-forming regions in nearby galaxies are compared to composite spectra of Lyman-break galaxies (LBGs), binned by strength of Lyman alpha emission and by mid-UV luminosity. Several far-UV spectral features, including lines dominated by stellar wind and by photospheric components, are very sensitive to stellar abundances. Their measurement in Lyman-break galaxies is compromised by the strong interstellar absorption features, allowing in some cases only upper limits. The derived C and N abundances in the LBGs are no higher than half solar (scaled to oxygen abundance for comparison with emission-line analyses), independent of the strength of Lyman alpha emission. P V absorption indicates abundances as low as 0.1 solar, with an upper limit near 0.4 solar in the reddest and weakest-emission galaxies. Unresolved interstellar absorption components would further lower the derived abundances. Trends of line strength, and derived abundances, are stronger with mid-UV luminosity than with Lyman-alpha strength. H2 absorption in the Lyman and Werner bands is very weak in the LBGs. Template H2 absorption spectra convolved to appropriate resolution show that strict upper limits N(H2)< 10^18 cm^-2 apply in all cases, with more stringent values appropriate for the stronger-emission composites and for mixes of H2 level populations like those on Milky Way sight lines. Since the UV-bright regions are likely to be widespread in these galaxies, these results rule out massive diffuse reservoirs of H2, and suggest that the dust/gas ratio is already fairly large at z~3.Comment: Astron J., in press (June 2006
